Abstract :Methacrylate-benzodioxinone insert ignore into journalissuearticles values(BDMA); as a monomer was firstly synthesized and then copolymerized with methyl methacrylate and 2-hydroxyethyl methacrylate via atom transfer radical polymerization insert ignore into journalissuearticles values(ATRP); in the presence of CuCl/pentamethyldiethylene triamine insert ignore into journalissuearticles values(PMDETA); catalytic system using ethyl 2-bromopropionate insert ignore into journalissuearticles values(EtBrP); as an initiator. Successful formation of the block copolymer was also confirmed in detail by proton nuclear magnetic resonance spectroscopy insert ignore into journalissuearticles values(1H NMR);, Fourier-transform infrared spectroscopy insert ignore into journalissuearticles values(FT-IR);, and gel permeation chromatography insert ignore into journalissuearticles values(GPC); appropriately. Secondly, photochemical acylation of obtained copolymer through hydroxyl and benzodioxinone groups led to the release of benzophenone compound and ester-linkage on the polymer backbone. The formation of ester-linkage increases the glass transition temperature and the thermal stability of the obtained copolymer.
